MAINTENANCE SCHEDULE FOR THE IDH2 RANGE

INDUSTRIAL DIESEL HEATERS

Download the Maintenance Schedule & Logbook

For Your Information

Due to poor quality diesel available in some regions in Australia and the continuous ‘winter diesel problems’ we face each year such as ‘wax crystallising’, which can lead to fuel line blockages etc, regular maintenance and adhering to our strict guidelines which include storing & preventative wax crystallising options is highly recommended to ensure the best performance and longevity of our Diesel Heaters.

All diesel fuel contains wax. It is considered an important diesel component because of its high cetane value. Normally the wax is a liquid in the fuel, however, when diesel fuel gets cold enough the wax starts to crystallise (i.e. solidify). If the temperature is sufficiently low, enough crystals will form to block the fuel filter, fuel line or nozzle.

It is recommended a qualified service center or persons complete any maintenance & servicing works. However the above recommended maintenance schedule can be completed by the end user.
Any electrical works must be completed by a qualified person only. No electrical components or parts are to be serviced or removed by the end user. If the plug or lead is damaged do not replace, contact Fanmaster or have a qualified persons complete the work.
If claiming under warranty please contact Fanmaster or where you purchased the heater from first. The logbook must be completed and supplied when claiming under warranty.

How to identify waxing problems

  1. If wax has formed in a diesel fuel then it will block fuel lines and filters, it is visible as a white/yellow deposit or cloud in the fuel.
  2. The heater will be hard to start or will not start due to fuel starvation

Recommended Maintenance Schedule

  1. High frequent use, colder regions or dusty/dirty environments will need to be checked on a more regular basis.
  2. When cleaning fuel lines, fuel filters, fuel nozzle it is recommended to rinse or soak in diesel or kerosene. If using water please ensure the parts are completely dry before re-installing.
  3. After use do not leave your heater out in the cold, store away inside and cover it with a tarp or blanket (after its cooled down). This will assist in melting the fuel in the fuel lines and prevent any blockages.
  4. After winter or for long periods of non use do not leave any diesel fuel in the tnak, use it all up or drain the tank.

Blending Diesel

If you are in low temperature regions such as Alpine/highland/inland or unseasonably cold weather, a diesel blend with kerosene may provide some relief to lower the cloud point.
